The present invention discloses aromatization reactor vessels with hydrogen membrane tubes, and associated aromatization reactor vessel systems. Also disclosed are processes for conducting aromatization reactions utilizing these reactor vessels and systems.

In order to suppress discharge of an unreacted content in a chemical reaction apparatus for irradiating a content with microwaves, a chemical reaction apparatus includes: a horizontal flow-type reactor in which a liquid content horizontally flows with an unfilled space being provided thereabove; a microwave generator that generates microwaves; and a waveguide that transmits the microwaves generated by the microwave generator to the unfilled space in the reactor, wherein the inside of the reactor is partitioned into multiple chambers to by overflow-type partition plates and that allow the content to flow thereover and an underflow-type partition plate that allows the content to flow thereunder.

The present invention discloses aromatization reactor vessels with hydrogen membrane tubes, and associated aromatization reactor vessel systems. Also disclosed are processes for conducting aromatization reactions utilizing these reactor vessels and systems.

The present invention relates to a process for converting natural gas to higher hydrocarbon(s) including aromatic hydrocarbon(s) in n reaction zones operated in series, wherein m reaction zones are not participating in the conversion process and only (nm) reaction zones are operated under reaction conditions sufficient to convert at least a portion of said natural gas to an effluent having said higher hydrocarbon(s). An object of the present invention is to provide a process for converting natural gas to higher hydrocarbon(s) including aromatic hydrocarbon(s) wherein a high reactant, i.e. methane, conversion can be achieved.

This disclosure relates generally to processing of gas using packed bed column, and more particularly, a packed bed column with stacked packed channels for processing gas. In current packed bed column configurations, the problems of maldistribution of gaseous stream across the packed beds and channeling associated with the packed beds results in high power requirements and operating expenses. The present disclosure includes gas distribution mechanisms and stacked packed channels for proper gas distribution and channeling of the incoming gaseous stream. The gas distribution mechanisms ensure that the incoming gas gets distributed evenly to the packed bed. This greatly increases the productivity of the process and increases the process efficiency as more area is available for heat and mass transfer to take place. The disclosed configuration is used for gas separation via adsorption, thermal energy storage applications and so on.

Processes and systems related to solid phase peptide synthesis are described. The processes include a flow-through process comprising cyclic addition of amino acids to a column packed with resin, wherein each cycle includes the combination of the amino acids with one or more reagents to provide an activated amino acid mixture, and wherein heating is applied to the amino acid(s) before they are passed through the column and wherein the amino acids are re-circulated at least once over the column packed with resin. Systems for such processes are also described.
